THE USE OF MULTI-TEMPORAL SENTINEL SATELLITES IN THE ANALYSIS OF LAND COVER/LAND USE CHANGES CAUSED BY THE NUCLEAR POWER PLANT CONSTRUCTION

We investigated the impact of Wind Turbines and Wind Turbine Interference on operational weather radar unfiltered raw IQ-data and subsequent radar moments, such as Reflectivity, Differential Reflectivity, Differential Phase, Mean Doppler Velocity and Correlation Coefficient, for both events with and without precipitation in this contribution under the scope of the RIWER (Removing the Influence of Wind Park Echoes in Weather Radar Measurements) project.

The current work presents a structure that can be used in magnetically coupled bi-directional data transfer structures. It allows for high-speed data transfer with high decoupling between both data channels and thus provides a highly reliable data link. The principal used to achieve the decoupling is the cancellation of magnetic fields generated by one part of the structure in the other part and vice versa. Three dimensional field simulations and measurements at a prototype were conducted.

In this paper, a novel approach (using metamaterials) is used to enhance the XPD for a dual linear polarization patch antenna at the frequency of 10 GHz. This improvement is obtained by placing two S-RRs close to the microstrip patch antenna, placing a SRR between two microstrip feed lines, and etching two pairs of CSRRs in the ground plane. An improvement in the XPD by 8.8 dB as compared to the conventional dual linear polarization antenna is noticed.
